Frustration and fear

My husband and I have been TTC for 6 months! I know I know sometimes it can take a while. But here is why I am frustrated/scared.

He has a daughter with his ex so I know his swimmers work. So I fear there is something wrong with me. I have followed all my ovulation schedules taken ovulation test and still no luck.

My whole life my biggest dream was to become a mom to my own child. My biggest fear has always been not being able to get pregnant. Do I’m slightly freaking out and possibly for no reason.

When is a good time to discuss these concerns with my doctor?

Does anyone else have an irrational fear of infertility?
